This short video shows the movements of short beaked common dolphins Delphinus delphis recorded by Tethys researchers around the island of Kalamos, in western Greece, between 1997 and 2007.

While research effort in this area has been increasing over the years, common dolphin numbers showed a continuous decline, dropping from about 150 animals in 1996 to only 15 in 2007.

Management action is urgently needed to prevent the complete eradication of common dolphins from this part of the Mediterranean Sea - one of the last places where these beautiful and endangered marine mammals still survive.
